The cutter 17 is operable to penetrate or cut an openingin an end of a container C pushed or forced downwardly onto it so that the contents of the container may discharge directly into the receptacle R. Thecutter 17 is mounted or supported on the anges 22 and projects upwardly a considerable distance above `theftop ofthenreceptacle R, The cutter 17 is substantially U-shaped in'V horizontal cross section having spaced vertically disposed side parts 27 and a curved outer part 28Yconnecting the,r spaced parts 27. It is an important feature of the invention that the cutter vr17 is inclined downwardly and inwardly toward apoint inthecentral vertical axis of the recep- 4 tacle R so that the force exerted on the cutter in "opening the container C is directed inwardly and diagonally relative to the receptacle R, and has no tendency to tip or upset the receptacle R.

tance outwardly from the. cutter 17. In the embodiment of the invention being described, `the guide Vlis integral .with the `body 16; The guide 18 is inclined upwardly and outwardly at the same angle `as the cutter 17 and-isxspaced'outwardly p fromfthe cutter a` sufficient distance to-pass the bead of the container .C with suitable sliding. L clearance.` The inner surface. or `.side of the guide `18 is adapted to `be engaged. by the lcontainer C and is shaped so as to eiectivelyguide thecontainer on to the cutter 17 and to steady or `stabilizethe container during its downward movement. A

i The guidelmay be shapedandproportioned iso asrto guide containers of'anyparticularor specific 'shape on to thecutter 17.. In'thev particular case illustrated in the drawings; the guide 18. is of curved horizontal cross section so as to handleor guide cylindrical containers. VThe diameter of curvature of the guide 18 is preferably sufficiently large to allow the guide llto` accommodate cylindrical containers var-ying considerably in size and to permitjthe device to be used in opening containers ofA rectangular or polygonal Vcross section in the manner -illustrated in Fig. 7.

In the form of the invention illustrated in the drawings, the guide 18 extendsl from one end of the body 16 to the other and projects a substantial distance above the upper. endV of' the cutter 17.

VThe. upper end of thefguide 18 may be suitably curved as illustrated `in the drawings.` .It will be' apparent that the guide l'operatesto shield the cutter 17 `and to prevent accidental contactwith .45 the invention illustrated inFlgs. 1 to 4r-inclusive.

the cutter.

It is believed-that the operation of the form-of of the' drawings will be readilyfunderstood from the'foregoing detailed. description.. To open the container C, itis slid downwardly on the inner surface 40 of the guide 18 so thatthe point 320i the cutter penetrates thejend 36 of the container at apoint immediately adjacentthe bead 35.-v A

`downward and inward pressure or pushon the upper end of thezcontainer C forces itdownwardly on the cutter 17 so that the cutting edges 31 of the cutter operate to makeY a I J-shaped.` cut. AS described above, the cutter in. being sharpened at its inner-side to provide the edges 31, operates to roll the material between the sides ofthe cut inwardly the manner-illustrated in Fig. 2 ofV thedrawe ings. The guide 18 4operatesto hold1the container C in proper-cooperation with the cutter 17 as it is forced downwardly on the. cutter.` The force or pressureexertedon the container Cwhen `it is pushed on tothe cutter 17 acts downwardly and inwardly toward the centre of the receptacle R and does vnot cause the receptacle to be tipped or overturned. Itislpreferred to push the-con'- Vtainer C downwardly and inwardly on the cutter "17 atapproximately the same angle as the guide 18, and the cutter;` however, a straight downward p forceiexerted onthe container-.Cduring opening of the containerv will not `c ive'rturn the receptacle 1RorfpreVentA-the proper operation of the cutter l `17,"asatll1eguide 18 operates toi guide the cutterV downwardly an'inclined or tipped position `and `maintain it in proper cooperation with the cutter.

As the opening is `formed in the bottom orendi36 of the container C, thecontents of the container.

. Y discharge or drain down'wardly through the lower guide and maintain `end of the cutter and between the flanges 22 directly into'the receptacle R.".The material be-.f

tween vthe spaced parts of the guide, in being'rolled` back as indicated at X in Fig.:2 of the drawings,

provides a large unobstructed opening in the end of the container in directvertical alignment with.: the space between the sideparts 27 of the cutter. and the body flanges 22'. vThe drainage-opening 33 in the cutter 17 permits the free discharge and .draining Y'of .the contents of the container (fromY thecuterside vof thecutter.. Asthe container C` `i'stipped or inclined,V itscontents may freely. drain 'through `the opening formed by the cutter 17." There is no upsta'ndingridgeor bead formed alongt the longitudinal and' lower edges of the opening madeby the cutter 17, and fluid cannot betrappedinthe lower end ofthe inclined container. Very.

' little force or pressure is required to push the vcontainer on to the cutter and the container is` easily removed from the cutterafter being opened and drained. In practice, the cutter 17 makes an jY opening in the end ofthe container thatexte'nds i inwardly from the bead 35 and thus allows for the drainage Vof all the liquid from the container. The' device, may be easily .and 'quickly applied to dispensing receptacles or 'measures now in use or maybe embodiedin the receptacles when manufactured. The cutter 17 isattached tovthebody 16 so Vthat it may be readily removed for replacement or sharpening.v The`V device does not pro-` Figs. 51and 6 of` the drawings illustrate afspring or clip fastening means for detachably connecting the body 16a of thedevice with the handle 14 of the receptaclahA clip is attached to theunder side of the body projection 24E andis substantially Ushaped,'having a lower'part 51 adapted toengage under the upper portion 15 of thehandle.
